Vitamin B12 in nutrition is exclusively of animal origin (except in some supplements which are also suitable for vegetarians and vegans); it is formed by bacteria in the digestive tract of animals.
Older people take vitamin B12 from a supplement better than from food. People who eat vegetarian, generally receive less vitamin B12 inside. In such situations, supplementation with a B12 supplement also help.
Vitamin B12 contributes to the reduction of fatigue and supports the energy level. B12 is also good for the homocysteine metabolism, the formation of red blood cells and the cell division process. The vitamin in addition, has a positive influence on the functioning of the immune system. Finally, it contributes to the mental resilience.
Vitamin B12 with folate
Vitamin B12 has a strong synergistic effect in the body with folate. Therefore, it is in most cases of interest to include in these nutrients combined. This is possible by a loose B12-product in combination with taking a multi-vitamin, or by the use of only a product with B12 and folate. This lozenge contains in addition to the two active forms of B12 also 500 mcg 5-methyltetrahydrofolate (5-MTHF) in the form of Quatrefolic®. 5-MTHF is the form of folate already converted. That's a big advantage because not everyone is the synthetic form of folate, which is often used in supplements, can convert well. Quatrefolic® is bound to glucosamine salt for optimum stability and absorption.
